Abstract
The process of the pivoting friction of ShKh15 steel over the flat surface of a prism made of R6M5 steel was studied and an analytical description of interaction of the pivoting friction moment with the radius of the wear scar, load, and time of loading was proposed. In the steady wear mode, the pivoting friction moment is steady as well. Change in the pivoting friction moment does not stay within the boundaries of one linear dependence, and several linear regions are observed and they may be interpreted by the law taking into account the moment of resistance to pivoting dictated by the tangential component of the equivalent forces of the molecular attraction of the friction surfaces.
